Chunk-Based Minibatch

flute -> violin with time chunk size 4 and channel chunk size 0

flute -> violin with time chunk size 4 and channel chunk size 32

violin -> flute with time chunk size 4 and channel chunk size 0

violin -> flute with time chunk size 4 and channel chunk size 32

Impact of Different Sigma Max and Sigma N

violin -> noise -> flute (with sigma_N=100)

violin -> flute
